a. 28 * 63
28 (60) + 28 (3) or 20 (60) +20 (3) + 8 (60) + 8 (3)
1680 + 84=1764 1200 / 60 +480 +24=1764
b. 17(59)
17 (50) + 17 (9) or 10 (50) + 10 (9) + 7 (50) +7 (3)
850 + 153=1003 500 + 90 + 63 =1003
c.458 (15)
458 (10) +458 (5) or 10 (400) + 10 (50) + 10 (8) + 5 (400) +5 (50) + 5 (8)
4580 +2290 = 6870 400 + 500 + 80 + 2000 + 250 + 40 = 6870
My work is kinda confusing but hope it helped
Answer:
48
Step-by-step explanation:
The consecutive numbers will be x and x + 1. Then write out the equation 2x + 1 = 99
Collect like terms
2x = 99 - 1
2x= 98
divide both sides by 2
x = 49
10/16 = t /40
where t is the time in minutes that they will get to the front of the line.
Answer:
Step-by-step explanation:
n = 3 => f(n) = -4*-3+8 = -44
n= 0 => f(n) = -4*0+8 = 8
n= 2 => f(n) = -4*2+8 = 0
n= 7 => f(n) = -4*7+8 = -20
